I think probably what we need to do, rather than shove the pkg-config
results willy-nilly into our flags, is to disassemble them like we do
with the same results for xml2. If you ask me, the way we are handling
ICU flags is a poor precedent that is going to blow up at some point;
the only reason it hasn't is that people aren't building --with-icu that
much yet.
